| 摘 要： | 在传统单开关三相DCM BOOST电路开关的理论基础上．利用软开关技术构成一种新型的三相BOOST低谐波高功率因数的ZVCT—PWM变流电路并分析其原理，进而设计一种离散控制方案来控制电路的工作状态．利用仿真软件Matlab进行仿真实验，并作谐波分析，通过实验得到加入软开关变换电路后，降低输入电流的总失真，电路工作在单位功率因数状态下，有效抑制谐波的产生．

| Abstract: | On traditional switch circuit theoretical foundation of single switch DCM BOOST of three phase,the article utilizes soft switch technology to form a new type with low harmony wave and high power factor,BOOST of three-phase,of transformed current circuit,analyses its principle,and designs a kind of dispersed working state that control the scheme in the control circuit.It utilizes emulation software Matlab to carry on emulation experiment and harmony wave analysis.Through the experiment,after adding soft switch transformed circuit,total distortion of input current is reduced,the circuit is operated under unit power factor,and suppresses the harmony wave effectively. |
